There's no one way to create a story on brainstorm. The best way to start is to come up with a basic idea or concept for your story. Once you have that, you can start fleshing out the details. Who are the main characters? What's the basic plot? Where does the story take place? What elements will make your story unique?
Once you have a good understanding of your story, you can start writing it out. The best way to do this is to just start writing and see where the story takes you. Don't worry too much about making things perfect, just let the story flow and go with the flow. You can always revise and edit later.
If you get stuck at any point, there are plenty of resources available to help you out. There are online forums, writing groups, and even online courses you can take. And of course, there are always books on writing that can give you some great tips and ideas. Just remember, there is no one "right" way to write a story. So just relax, have fun, and let your creativity flow.
